The success model Kiaro is hitting the roads with an extra boost now. The Pmax version runs on a minimalistic drive unit by Ebikemotion on the rear wheel as well as a barely noticeable 250-Wh battery in the down tube – integration at the highest level! This “total package” offers the perfect combination of low weight and optimum support. Especially on the mountain, nothing can stop you anymore on the Kiaro Pmax.

The price reduction shown refers to our RRP in the last regular model year. The prices displayed have already been reduced.


Who’s the Kiaro Pmax perfect for? And what makes the e-roadbike so special? We’ve got the answers for you: Headwind, tough mountain stages, riding with riders of different levels of ability: There are many reasons to get the new Kiaro Pmax with built-in tailwind. What’s more, the slim battery takes up so little space that the difference between the Kiaro and a bike without drive unit is barely noticeable. Another highlight: its low weight. It weighs in at only about 10.7 kg – simply incredible! What else does the e-roadbike made by Simplon’s team of tinkerers have to offer? Let’s find out! 


  • For the Kiaro Pmax, Simplon relies on the Flat Mount Standard for optimum integration of the brake – perfect for the aerodynamics of the roadbike. 
  • The compact 2-kg hub drive unit by Ebikemotion is seamlessly integrated between sprocket cluster and disc. It reaches a torque of up to 40 Nm and supports the rider especially on mountain passages at a speed of up to 26 km/h. When not in support mode, the motor rotates practically without any resistance and allows for efficient riding on flat terrain – just like a standard roadbike. 
  • Battery management is particularly smart: Hidden in the downtube, there’s a 250-Wh battery. If you need more power for longer tours, you can mount one or two range extenders at the two bottle cage positions and increase the capacity to up to 670 Wh.
  • The control unit is perfectly integrated into the top tube. Via a button, you can select between three levels of support and the display shows you the battery capacity. Optionally, the system can be hooked up to your smartphone via an app, which gives you several additional functions. 
  • The prominent fin on the left side of the bottom bracket ensures optimum torsional rigidity and maximum propulsion. 
  • Design and function are unique: Fork and frame blend in with each other and seem as if they were made from one piece. The fork has a particularly round and soft look which ensures appropriate fibre alignment at the transition of the crown race and the lower bearings. This significantly increases stability and stiffness of the fork. 


Cherished and loved: the innovative technologies by Simplon. The Kiaro Pmax boasts a number of high-end highlights: The optional steerer-stem unit in combination with internal cable routing via the headset gives the bike a super clean look and prevents the cables from getting tangled. Thanks to the Comfort Concept, the bike offers highest sitting comfort. Top tube, seat stays and seat tube constitute a beautiful unit at the point where they merge. The Raptor Dropout technology – rear-facing dropouts – ensures a higher vertical flax and more comfort at the fork, which is especially helpful when riding over road bumps. 


There are many optional features available for the Kiaro Pmax. How about a range extender, for instance? An additional 250 Wh significantly increase the range of the e-roadbike. By the way, the additional battery can be attached right at the charging socket.

*STR: The higher the number, the more upright is the seating postion.
Due to the integrated seatpost clamping without the otherwise usual "seat tube stub", the dimension "A" is shorter than the corresponding frame height.
On the KIARO DISC, KIARO PMAX and PRIDE ll models, the top tube is sloping, which results in a difference between the frame size and the "A" dimension.
